Hello Ralf, Jayachandran, Ganesan

Here are two small fixes for modular USB and AHCI builds that I encountered
while playing with a FVP board.

These are based off upstream-sfr/mips-for-linux-next

Thanks!

Commit 1004165f346a ("MIPS: Netlogic: USB support for XLP") and then
commit 9eac3591e78b ("MIPS: Netlogic: Add support for USB on XLP2xx")
added usb-init and usb-init-xlp2 as objects to build when CONFIG_USB is
enabled.

If CONFIG_USB is made modular, these two files will also get built as
modules (obj-m), which will result in the following linking failure:

ERROR: "nlm_io_base" [arch/mips/netlogic/xlp/usb-init.ko] undefined!
ERROR: "nlm_nodes" [arch/mips/netlogic/xlp/usb-init-xlp2.ko] undefined!
ERROR: "nlm_set_pic_extra_ack" [arch/mips/netlogic/xlp/usb-init-xlp2.ko]

undefined!
ERROR: "nlm_io_base" [arch/mips/netlogic/xlp/usb-init-xlp2.ko]
undefined!

Just check whether CONFIG_USB is defined for this build, and if that is
the case, add these objects to the list of built-in object files.

Commits a951440971d0 ("MIPS: Netlogic: Support for XLP3XX on-chip SATA")
and fedfcb1137d2 ("MIPS: Netlogic: XLP9XX on-chip SATA support") added
ahci-init and ahci-init-xlp2 as objects to build when CONFIG_SATA_AHCI
is enabled.

If CONFIG_SATA_AHCI is made modular, these two files will also get built
as modules (obj-m), which will result in the following linking failure:

ERROR: "nlm_set_pic_extra_ack" [arch/mips/netlogic/xlp/ahci-init.ko]

Just check whether CONFIG_SATA_AHCI is defined for this build, and if
that is the case, add these objects to the list of built-in object
files.

We have a slightly different fix for this in our internal repository, I
was planning to submit it soon:

+obj-$(subst m,y,$(CONFIG_SATA_AHCI))	+= ahci-init-xlp2.o

This will add the init code when USB or SATA is enabled as module or
is built-in, so I think this is be a better solution.

Not sure which one is "better" than the other since they both solve the
same problem, but whatever works for you also works for me! The tree
seems to have a mix of both approaches.

Thanks!
